Sorry, Wally, I don't have any such thing to upload. Your browser should be letting you save the files as lineart.ps (or as anything else you choose to name them), Then googling postscript viewer gives me "About 3,550,000 results". Probably at least one is for your OS (I'm using linux and would guess the odds are you're using windows). ghostview (also called gv) is maybe the most common free/opensource one. And I'm sure there's a windows version. But I don't know whether it's a "one click" install on windows, or has lots of dependencies (which would probably be mostly fonts files) that would make installation a chore. Maybe try a postscript ng for more info (or maybe somebody will followup here). -- John Forkosh ( mailto: j@f.com where j=john and f=forkosh )
